Public Process and Collaboration

Public Process ⌘

• Represents the interactions between a private Business Process and another Process or Participant
• Only those Activities that are used to communicate to the other Participant(s) are included in the public Process
• All other “internal” Activities of the private Business Process are not shown
• Public Process shows to the outside world the Message Flows and the order of those Message Flows that are needed to interact with that Process
• Public Processes can be modeled separately or within a Collaboration to show the flow of Messages between the public Process Activities and other Participants
• Called “abstract” in BPMN 1.2.
• Public Process is orchestrated by the private processes (as oppose to Collaboration)

Collaboration ⌘

• Depicts the interactions between two or more business entities
• Contains two or more Pools
• Can be shown as two or more public Processes communicating with each other
• The corresponding internal (executable) Processes are likely to have much more Activity and detail than what is shown in the public Processes.
